e-RATOS (Embeddable Remote Automatised Teaching and Controlling System) This is a web-based application that provides a rich extensive toolset for students' knowledge control via classical tests. The app can be used by medium and large educational organisations like schools, colleges or universities in multiple or mixed knowledge domains: health care, linguistics, natural sciences, etc. with significant loading like 10000+ learning sessions per day, with 1000+ simultaneous active sessions of 20-200 questions, accessed from within any LTI 1.x-compatible LMS like edX, Moodle, Sakai, etc.
(LTI v 1.1 is deprecated and transition to LTI v1.3. is desired) as well as directly from within Intranet or Internet network via a browser.

• Java 17;
• Spring Boot 3.x;
• Hibernate;
• RDBMS (MySql 8.x);
• Redis 7.x
• Maven;
• Junit 5 (Jupiter);
• TestContainers.

• React.js (sources here)

Varies depending on the scale of your organization: quantity of simultaneous users and quantity of questions. E.g. for an organization of 10000 concurrent students, and staff of 500 people with questions base of 500000+, minimal requirement is the following:

• RAM 16Gb, with heap size > 8Gb;
• Single quad core CPU;

Here

Use tags:

• latest (for latest image)
• prod (for least stable image)

Warning!

You need to create a Docker hub account to access the image.

Docker file creation with Jib Maven plugin info:

• Set application.yml -> profile=stage/prod
• ./mvnw clean compile [Jib requires compiled project]
• ./mvnw jib:build -Djib.to.auth.username=${DOCKER_HUB_USERNAME} -Djib.to.auth.password=${DOCKER_HUB_PASSWORD}

(Specify you credentials from DockerHub)

• prod
• stage
• dev

Notes(!): prod profile is tied to AWS environment (see ElastiCache Redis config).

• Make sure to use JDK 17 in the project;
• Install EnvFile plugin;

SpringBoot config

• Add SpringBoot configuration
• Enable env. variable file
• Add env file as the .env file
• Set up MySql database locally (v 8.x)
• Run locally

Docker-compose config info:

• Add Docker-compose configuration
• Specify docker-compose.yml
• Specify .env variables file
• Run locally

BE only

• Install Docker runtime
• Install Docker-compose
• Put .env file with all required environment variables into the same folder where docker-compose.yaml is located.
• Run docker compose up -d to start the app;
• Run docker compose down to stop the app;

Fullstack

• Run docker-compose -f docker-compose-fullstack.yaml up -d to start the fullstack app with front-end part;

(Make sure to use Java 17 as default system JDK)

export JAVA_HOME=/usr/lib/jvm/java-${JDK_VERSION_PACKAGE}

export PATH=$JAVA_HOME/bin:$PATH

java -version

Unit tests

./mvnw clean test

IT tests

By config, all test classes ending with *TestIT will be executed!

./mvnw clean verify

Local Terminal run

• Export env. variables from .env file

export $(grep -v '^#' .env | xargs)

• Run the app via Maven

./mvnw spring-boot:run

./mvnw flyway:clean -Dflyway.user=${DATABASE_USER} -Dflyway.password=${DATABASE_PASSWORD} - clean local DB

./mvnw flyway:migrate -Dflyway.user=${DATABASE_USER} -Dflyway.password=${DATABASE_PASSWORD} - migrate local DB

./mvnw flyway:validate -Dflyway.user=${DATABASE_USER} -Dflyway.password=${DATABASE_PASSWORD} - validate local DB

(Specify you credentials from DB)

Alternatively, locate settings.xml (with DB credentials) in .m2 folder on local PC
